Patented June 13, 1933 UNITED STATES PATENT OFFICE WALTER F. HEROLD, OF BRIDGEIPORT, CONNECTICUT, ASSIGN'OR TO THE BASSICK j COMPANY, OF BRIDGEPORT, CONNECTICUT, A CORPORATION OF CONNECTICUT CUSHION SLIDE FOR- FURNITURE Application filed December 18, 1931; Serial No. 581,803.

The present invention relates to cushion slides for furniture, and has for an object to provide a slide of simple and inexpensive construction and which may be attached with t facility, ierely by driving with a hammer. Another object is to provide a cushion slide which will permit tilting of the furniture without loosening, and which will at all times remain firmly in place without loose- Q nessor rattling, irrespective of whether the slide is in engagement with the floor or not. A further object is to provide a slide having an attaching nail loosely but permanently secured to the metal shoe of the slide, 215 and to this end propose to secure the same by swedging the metal of the shoe in a man ner to greatly facilitate assembly and provide a reliable connection between the shoe and the nail. A still further object is to .29 provide interlocking means between the floor engaging base or shoe and element, whereby the latter will at all times remain centered and will not slide or shift its position during tilting or movement of the cushion 3 the slide, so that the outer peripheral surface will present a uniform, smooth and flush appearance.

Similar reference characters indicate corresponding parts throughout the several figures of the drawing.

Referring to the drawing, the cushion slide, according to the present embodiment of the invention,

comprises a metallic base or shoe 10, preferably of circular form, having a flat upper surface 11, and a substantially flat nontiltinglower floor-engaging surface 12. A socket 13 having a flat bottom surface is provided centrally of the upper surface, its side walls being contracted at the top, and within this socket the head 14 of thedriving nail 15 is loosely engaged and retained, the dimensions of the socket being such as to allow free up and down and tilting movement of the nail. The under surface of the nail head 14 is preferably flat and its upper surface is rounded in the form of a section of a sphere. An annular groove 16, substantially semi-circular in cross-section, is provided in the upper surface in concentric relation between the socket and the outer periphery. I

At the upper side of the shoe a cushion layer 17 is provided, which may be of soft rubber, cork, or other suitable materiahthe same conforming at its outer periphery to the shoe and having a central aperture 18 snugly engaged by the nail under slight compression, so that in the unattached relation shown in Fig. 1 the cushion layer is frictionally retained upon the nail. An annular rib 19 of semi-circular cross-section, is formed upon the under surface of the cushion layer 17 and in adapted to interlockingly engage the annular groove 16 of the base or shoe to center the cushion layer and prevent any lateral sliding or shifting, so that the adjacent peripheral edges of the two parts remain flush with each other under all conditions.

In Figs. 6 and 7 I have shown the manner of assembling the nail and metal shoe. The side wall of the socket 13 is cylindrical, before assembly, and an upstanding flange 20 is provided at its upper edge. The nail head is insertedin the socket and by means of a suitable swedging tool the flange 20 is flattened, causing the inner wall of the socket to contract at its upper end, so that the nail head is locked in place.

The operation is as follows Before attachment to the leg the parts of the slide are in the relation shown in Fig. 1, the nail being frictionally held by I the cushion element 17 so that the flat head engages flatly against the flat base of the socket 13 when the cushion is in contact with the upper surface of the base or shoe 10. The interlocking relation of the rib 19 and groove 16 retains the parts in this relation preparatory to driving into the leg, the nail being thus solidly supported centrally against the base or shoe in perpendicular relation thereto.

In driving the nail into the furniture leg the blows directed against the surface 12 of the metal shoe are directly transmitted to the nail head, so that the same may be firmly and accurately driven substantially in the same manner as would be the case if the nail were rigidly fixed to the base. After the nail is driven to a point where the cushion element 17 contacts with the end of leg, further driving compresses the cushion element, so that upon its expansion after the driving operation the head of the nail assumes a position in spaced relation above the base of the socket and abutting the contracted end of the socket, as clearly indicated in Fig. 4, the cushion element being under slight compression to maintain this relation and thus eliminate looseness and rattling. Upon tilting of the leg as shown in Fig. 5, the cushion is compressed at one side, the'rounded upper surface of the nail head sliding smoothly over the contracted end of the socket. Lateral shifting or sliding movement between the base and the cushion element is prevented by the interlocking rib and groove under all conditions of use.

I have illustrated and described a preferred and satisfactory embodiment of the invention, but it will be obvious that changes may be made therein within the spirit and scope thereof, as defined in the appended claims.

Having thus described my invention what I claim and desire to secure by Letters Patent is 1. A cushion slide for furniture, comprising a floor engaging shoe having a substantially flat top, provided centrally with a socket closed at its lower end and having a contracted upper end, attaching means comprising a nail adapted to be driven into the furniture by bloWs applied to said shoe having a head disposed and retained in said socket below said contracted upper end, and having free up and down and tilting movement relative to said shoe, a cushion layer at the upper side of said shoe having a central passage engaged by the shank of said nail and having a substantially flat under surface contacting the upper surface of said shoe, and interlocking rib and groove means cooperating between the upper surface of said shoe and the under surface of said cushion layer adapted to prevent lateral shifting movement one relative to the other.

2. A cushion slide for furniture, comprising a floor engaging shoe having a substantially flat top, provided centrally with a socket closed at its lower end and having a contracted upper end, and provided in out wardly spaced relation to said socket with an annular groove, attaching means comprising a nail adapted to be driven into the furniture by blows applied to said shoe having a head disposed and retained in said socket below said contracted upper end, and having free up and down and tilting movement relative to said shoe, a cushion layer at the upper side of said shoe having a central passage engaged by the shank of said nail and having a substantially flat under surface contacting the upper surface of said shoe, and provided in outwardly spaced relation to said passage with an annular rib interlockingly engaged in said annular groove of the shoe to prevent lateral shifting move- 7 ment one relative to the other.

3. A cushion slide for furniture, comprising a floor engaging shoe having a substan tially flat top, provided centrally with a socket closed at its lower end and having a contracted upper end, attaching means comprising a nail adapted to be driven into the furniture by blows applied to said shoe having a head disposed and retained in said socket below said contracted upper end and having free up and down and tilting movement relative to said shoe, a cushion layer at the upper side of said shoe having a central passage engaged by the shank of said nail and having a substantially fiat under surface contacting the upper surface of said shoe, and interlocking means cooperating between the upper surface of said shoe and the under surface of said cushion layer adapted to prevent lateral shifting movement one relative to the other.
